Re: 3750 Switch

Hello,

short of being a problem with your hardware, how do you have the connecting ports configured ? Can you post the configs ?

I have just recieved these switches they are out of the box. They will not be configured until summer. With vlan and so on. I just need to have them up and running for now..Thanks for the quick response

Re: 3750 Switch

Hello,

understood. Maybe the ports that are not functioning are in shutdown state ?

Re: 3750 Switch

Thanks, I perform the no shutdown command on those ports but only one side comes up. Any ideas what could cause this since they are at factory default?

Might be a problem with the auto negotiation.
